The Zebra Graphics Tablet: A Review

The Zebra Graphics tablet is a hardware
and software combination using the popular
Koala Pad graphics tablet--the same type
used with Radio Shack, Apple, Commodore,
and other computers.

The hardware portion consists of an I/O
board with two integrated circuits, a few
resistors and diodes, and two sockets into
which the Koala Pad is plugged.

The Koala Pad has a pressure sensitive
surface in the shape of your TV screen
which can convert the touched portion of
this surface to computerese which tells
the 2068 where to draw on the TV screen. A
special stylus comes with the pad, but any
blunt object (even your finger) works
well. Two buttons are also provided for
screen control (such as writing or
erasing). The drawing surface itself is
4.25" by 4.25". The entire unit is
slightly larger than the 2040 printer.

The important part is the software.
This is where the control comes in. The
package is supplied with Zebra Painter.
Zebra Painter takes the information sent
from the Koala Pad and allows you to draw
on the screen with the colors of your
choosing. You can also give coordinates to
make circles and straight lines.

Of the two control buttons, one is used
for draw/erase, and the other is for
command/select. You can choose what button
does what with the "LEFTY" command. The
screen commands are made by positioning
the drawing stylus such that the corres-
ponding pointer on the screen is over the
command word and pressing the command
/select button.

The keyboard commands are activated by
positioning the screen pointer over the
extreme right side of your menu and press
the command/ select button. You are then
prompted with "COMMAND?" So you type it in
on the keyboard. Keyboard commands
include: COPY screen to 2040 printer, CLS,
WRITE text on screen, LEFTY button swap,
STORE active screen to inactive screen,
RESTR inactive screen to active screen,
EXCHG inactive & active screens, SAVE
screen to tape, and LOAD screen from tape.

You can choose any color INK, PAPER,
and BORDER colors with screen commands and
change them at any time. You have two
sizes you can draw with, PEN is one dot

wide and high and BRUSH is five dots wide
and high. Precision drawing can be
accomplished by setting two points and
selecting the LINE command which draws a
straight line between the two defined
points. Circles can be drawn by defining
the center and edge. Directional drawing
can be vertical only, hori- zontal only,
or both.

Zebra Painter worked well and was’ easy
to use. I found that I had the best
control over the drawing by pressing the
pad with the stylus perpendicular to the
pad and don't rest any part of your hand
on the surface (it may confuse it).

This article is really more of a
software review of the different software
packages available for the Zebra Graphics
tablet. I also got Tech Draw and Zebra
Circus Coloring Book. Tech-Draw is the
program to get!

Tech-Draw was inspired by Apple's
MacPaint for the Macintosh computer. Like
MacPaint, Tech-Draw works in black and
white, so what you see on your TV screen
is what you get on your printer. Tech-Draw
provides up to 35 black and white shades
and patterns which gives you resolution to
one pixel.

Tech-Draw can be printed out on either
a large sized printer (with Aerco or
Tasword interface), or the TS-2040. Copies
to the large printer can be screen size or
turned sideways to fill up a whole 8 1/2
by 11 sheet of paper.

Pop-up menus are given when choosing

shades and patterns or brush sizes and
shapes (16). A FILL command is provided to
fill in enclosed areas with the current
shade or pattern. The shade and brush type
can be changed at any time. Text can be
mixed in with the graphics in three sizes
and fonts (normal, italics, or bold). The
current setting is always given in the
sample box. The UNDO command allows you to
undo the last segment done.

The different options are selected by

positioning the pointer over your choice
and pressing the select button. The
conmands listed in the ZebraPainter

section are also available in Tech-Draw
but everything except text is entered from
the graphics tablet itself.

I found Tech-Draw more enjoyable to use
than ZebraPainter. To satisfy my own
curiosity, and to test out the features of
Tech-Draw, I took a picture of a cat and
cut it down to fit the face of the cat on
the drawing surface and traced it onto the
screen! It worked remarkably well, when
you consider that I am no artist.

You can see from the sample that the
face was widened when transferred over,
but other than that, it traced very well.

I used as many of the different paint
brushes and shades as I could to aid me in
enhancing the drawing.

The manual which comes with Tech Draw
is very informative and contains many
ideas and sample pictures. Uploading and
downloading information for the modem is
also given.

Tne third program I got for use with
the graphics tablet was Circus Coloring
Book which is just a fun program in which
you go through and color in different
pictures as you would with a regular
coloring book.

At first I wasn't all that excited
about the system; I just didn't see any
use for it. But after I used Tech-Draw for
awhile and made the cat and a few other
drawings and discovered how easy it was to
Graw, I became very impressed and can see
all kinds of uses for it! Other than not
having a full 2068 edge connector feed-
through, I have really no complaints.

Once again, this works the same no
matter what computer its on. The software
is what makes it work so well. The
software (particularly Tech-Draw) is very
professional and puts this system in the
same league as say the MacPaint series for
the Apple, Speaking of Apple, it would be
nice if a mouse could be used with this

interface as well. Rumor has it that one
is being developed for the Spectrum in
England.

Fish Locator

A unique use of the Timex computer: tells you when, where and ~

how to catch more fish!

_SUM Magazine has received many differ-
ent programs for review. One of the most
original is Fish Locator.

Fish locator is a program that will an-
alyze the fishing environment in your area
from the date, weather, and coordinate
information you supply and give you a
comprehensive summary of the day's overall
fishing prospects. You are also provided
with two major and two minor solunar

fishing periods and the exact sunrise and
sunset times for the date requested.
Fishing for specific species is

provided for Bass, Walleye, and Northern
Pike. Another section covers the use of
baits and how to choose the right bait for
the type of fishing you plan to do.

You can also go back and repost your
concitions along with a different long-
titude and latitude for a different
locale. Fishing times for the whole month
can also be printed on the screen or to
the 2040 printer.

The program has a built-in directory of
75 cities in the U.S., Canada, and Alaska
to provide you with accurate coordinates
if you do not know them yourself. It comes
pre-programmed with the coordinates of
your area.

lastly, the program contains specific
suggestions for using the three most
common lures, i.e., spinnerbaits, crank-
baits and artificial worms.

When the program comes up running, you
are asked if the pre-programmed longitude
and latitude coordinates are to be used or
not. If not, you are given the choice of
coordinates of 75 cities to select from,

or you can enter your own exact
coordinates. Next you are asked to enter
the date and weather conditions: wind

speed, wind direction, temperature trends,
water surface temperature, current
barometric trends, current weather trends,
and water clarity.

Fish Locator then computes the day's
outlook figuring the overall outlook along
with the day's solunar times and sunrise &
sunset. At this point, you can get a_ hard
copy on the printer or continue. When you
continue, you get suggestions on where and
how to fish for the given conditions,
using different techniques and lures.

Next you are shown a main menu.
this you can choose:

From

1 Today's Prospects
2 Select a Species

U

3 Repost Conditions
4 Fishing times this Month
5 Select a Bait

Choosing Today's Prospects (1) gives
you what was just described. Select a
Species gives you specific tips on how to
fish for Northern Pike, Bass, and Walleye.
Repost Conditions takes you back to the
beginning and lets you change all your
variables.

Fishing Times This Month gives you a
summary of all the solunar times for the
month in question along with the full and
new moon. The last choice is Select a Bait
which gives you all kinds of hints on how
to use some of the more popular lures with
tips on what color to use and types of
water conditions to use them under.

Although I'm not an avid fisherman, I
can see that this is a valuable tool in
helping someone who is. It has been long
known that the changing of the tides and
the phases of the moon have had an effect
on fish (and animals). And now formulas
have been perfected to calculate when they
have the most effect over them, causing
them to seemingly lose much of their

natural caution. With this program, you
should be able to coordinate your fishing
times with those of the solunar peeks and
greatly enhance your fishing success.

The program is well-written and has

plenty of error trapping routines so as to
almost make it idiot proof. The program is
chocked full of information, although I
would like to see it cover more then just
the named species and lures. I personally
am planning a trip the end of July and
expect to do some fishing, with the help
of this program. I think it will help. The
documentation is good and states that the

program has been field tested for two
years.

How much would you expect to pay
for a dual 128K fast access storage
system for your Timex 2068 that
included Centronics and RS232
interfaces, Spectrum software and
buss emulation, and free word
processing software as standard?

*Wafadrive for the Sinclair Spectrum $154.95.
The Timex 2068 requires the new

Integrated System

The Wafadrive is a
complete system which
contains the micro interface,
two 128K drives, RS232 and
Centronics ports, all in one
attractively-styled, compact
unit. There is a minimum of
connecting leads and no extra
boxes to clutter the desk top.
Like the majority of profes-
sional systems, the units are
dual drive. This offers the opti-
mum balance between
system flexibility and cost.
Built-in serial and parallel
interfaces allow the direct
connection of just about any
popular printer.

Fast and Reliable

The Wafadrive achieves
very fast loading and saving,
but not at the expense of
reliability. Extensive research
and the use of high grade
materials ensure that the
Wafadrive will give years of
dependable operation. Data
integrity is on a par with
floppy disk. The fully inter-

changeable wafers are avail-
able in three sizes-128K, 64K
and 16K. Low capacity
wafers give faster access.
They are therefore most
suitable for program develop-
ment applications. The high
capacity wafers are suitable
for more general data storage.
Loading rate is approximately
2K per second-almost twice
as fast as similar products.

MTERM (Smart II)Telecommunications
— HINTS @& TIPS —

The MTERM Smart II telecommunications

program for the Timex/Sinclair 2068
personal computer is a fine value. This
software package exceeds the capabilities

of many terminal programs far exceeding it
in cost. And because of MTERM's wide
versatility, its users are still
uncovering more secrets of its power.

In these few pages are included hints

and tips as part of an addedum to my
manual entitled, "Timex Sinclair Smart
Terminal Telecommunications". These
additional insights are a compilation
obtained from the users of Smart LL
software and the author's experiences.

The following SMARTIPS are from Randy

& Lucy Gordon of the Timex/ Sinclair Users

Group, Cincinnati, Ohio:

* To get a file from a BBS you first need
to set your conversion to none. Toggle
your Buffer to open. Take in a file, then
close your Buffer. Next, escape to Basic.
The file should be saved like a normal
Basic program with SAVE "filename". You

will need the modem software to read this
file later.

* To view the file that you just saved to
tape, you must first LOAD the terminal
software, escape to BASIC and LOAD
"filename": PRINT USR 54016. This will
return you to the terminal program with
Buffer loaded. You must go to the Data
Buffer menu to view or print the file. [In

LOWEST PRICES for 2068 PRODUCTS!

* To receive a machine code listing the
set-up is the same as the Basic file,
except when you escape to SAVE to _ tape.
\The BASIC editor will appear as though it
has "crashed". (INVALID COLOR or NONSENSE
IN BASIC, ect.). Ignore this garbage and
SAVE "filename" CODE 26710, (the number of
bytes in the Buffer). Then you must Load

it back into the computer with Load
"filename" CODE (proper or normal
address), (number of bytes).

* To send a machine code program to

another Sinclair user you must first POKE
VARS, (53016) to leave room for Basic
overhead. POKE 23627, 24: POKE 23628, 207.
This gives a large Buffer to load Basic
in. Then you Load "machine code" CODE
26710:PRINT USR 54016. You must be in HEX
conversion. XMIT same as any other file.

* If by chance you can't get the dialtone
of your phone back, a 2050 modem relay may
be stuck open. Go to the main menu, press
SEM to exit to Basic and enter WITHOUT
line number OUT 119, 0.

* Some Bulletin Boards will not accept a

@ CTRL-R or CTRL-T to open/close the buffer
remotely. An alternative is to enter
CTRL-S to stop tramsmission, then return
to the Buffer menu and toggle the Buffer

open or closed as required.

* MTERM patches for both TASMAN and AERCO
parallel print interfaces are available
for download from the Timex Bulletin Board
on Zebra Systems. PHONE: (718)296-2229.

* One method of fixing all keyboard
entries to upper case is to go to XLATE
table §K# and change all lower case to
upper case. These values can also be
saved.

* The Bulletin Board SYSOP can read all
your messages, even private ones. If you
still want more privacy, how about sending
ciphertext or cryptogram messages? The
Smart II XLATE tabels facilitate
enciphering a message, and the recipient
to decipher it (provided they have the key
algorithm). The folowing elementary
example illustrates the principle
aa involved:

Rotate the alphabet counter-
clockwise by three letters,
so that A=D, B=E, C=F,.....,

11

X=A, Y=B, ect. Where = de-
notes "replaced by" as in
Basic programming.

If you send the PLAINTEXT
message,

TIMEX IS GREAT
The CIPHERTEXT would be
WLPHA LV JUHDW

To do this, change XLATE table §K% so all
keyboard entries will then be sent in
ciphertext. The recipient can read the
encrypted message by going to XLATE table
§I@ and changing it to the reverse, i.e.,
D=A, E=B, X=A, ect

* The Sinclair Basic commands IN and OUT
operate by port command assignments (e.g.
the assignments for the 2050 modem are 119
and 115 decimal). Using these commands you
can program the 2068 in Basic to
Autodial/Auoanswer thru the 2050 modem.
Using the same procedure, you can program
to redial, dial a sequence of phone
numbers, etc. The following list of OUT
command meanings is for reference:

OUT 119,0 - Hang up phone.
OUT 119,1 - Stop carrier
tone; do not hang up phone.
OUT 119,2 - Start carrier
tone.
ouT 119,3 - Open modem
relay contacts.
OUT 119,4 - Close modem
relay contacts.
OUT 119,31 - Take phone off
hook for dail tone.
OUT 119,34 - Start carrier
tone.

A typical application is programming a
5 cycle loop containing OUT 119,3 and OUT
119,4 in sequence. This would be the
equivalent of dialing the number 5.

Gremlins, the Adventure

First it was on the movie screen and now
it has made its way to your monitor
screen. GREMLINS, THE ADVENTURE is a
graphic/text adventure of the highest
caliber for the Spectrum from Adventure
International. It has made the most of the
graphic capability of the machine and pro-
vided a most amusing entertainment for the
whole family.

I had not at this point had any expos-
ure to any of the adventure type game pro-
grams for the computer and I find this one
a most pleasant introduction. Requiring
logic and a bit of skill, this is a change
from the shoot and run variety of arcade
games that most associate with computer
games. ;

The task at hand here is to rid the
town of Kingston Falls of Gremlins which
threaten to overrun it. If you have seen
the movie, it might help, but it is not
necessary.

At this point I (with the help of the
rest of the family) have found 27. graphic
locations and 6 text locations and elimi-

nated a few Gremlins...but Kingston Falls
is not safe yet.

The use of graphics in the program is
outstanding. It is clearly an amazing feat
in itself to fit this much in 48K and
still have enough left for a good adven-
ture. The icing on the cake is the use of
animation in many of the scenes.

On the text side, the ability to accept
more than one command per entry can speed
the game along a bit once you begin to
find your way around. Then if you find
your mind and fingers growing weary, you
have the option to save the game in pro-
gress to tape for continuation at a_ later
time.

REMEMBER...Don't let the Gremlins get
wet...they don't like light...and never
feed them after midnight!

GREMLINS is a lot of fun and I _ reconm-
mend it for first time adventurers and
veterans as well; even my brother-in-law
who is an Atari 800XL owner admitted that
he was impressed.

Gremlins is available from the English
Micro Connection, 15 Kilburn Court,
Newport, RI 02840. The price is $13.95 +
$1 for postage.

Unisort a sorting program

@ you can incorporate into

ee eons ene

ap oneer RUN and answer the prompts.

your own programs

"UNISORT" is a universal sort program. It
will do numeric as well as alpha sorts. It
is a utility program in that it has no
defined areas - they must be entered. The
program receives input to sort from tape
and will output the same. Sorted data is
saved in KS. The only holds are:

a. Max columns to sort is 32

b. Program uses 2056 bytes

c. Sort output will be in this order:
Numeric
Cap Alpha
Sm Alpha

d. File name max 6 chars.

Type program in just as shown. For tape
save of program, enter GOTO 9000 (will
save three times) then rewind tape and
verify.

Load program as "UNISORT". Once loaded,

Ist enter ROW count - if the array is
DIM(ed) (100,30), ROW count is 100.

2nd enter COLUMN count - if an array is
DIM(ed) (100,30), COLUMN count is 30

3rd enter END sort column - if area _ to
be sorted is columns 10 to 18, END column
is 18.

4th enter BEG sort column - if area to
be sorted is columns 10 to 18, BEG column
is 10.

Next request will be to enter array
file name - max 6 positions.
